Abstract
Asphaltene and oil shale are pyrolyzed at substantially atmospheric pressure for producing combustible products and carbonaceous material. A combustor combusts the carbonaceous material and produces flue gases which are supplied to a utilization device, and hot ash which is fed back to the pyrolyzer.
